A controversial bill requiring that publicly traded California companies include women on their boards of directors heads to the Assembly floor this week. SB826, which is opposed by many business groups, would make California the first state with such a mandate. State Sen. Hannah-Beth Jackson, D-Santa Barbara, the bill’s author, said it’s important for businesses to have a perspective from women — and time to “blow that glass ceiling up.” “By having more women on boards of directors, we can assure greater protections in the workplace against things like sexual harassment,” she said.
